I am myself is a victim of trusting too much with my friends, and i didn't realized that one of them are so jealous with me, and i just found out when i heard her talking about me and she even do not know im there listening, but its okay atleast i know it now and its a lesson for me that dont trust too much even with your friends.
DONT TRUST NOBODY!!!
To forgive someone who hurt you is easy but to trust them again is next to impossible. Sometimes trusting a friend is the hardest thing to do, even the closest friends can become enemies. When someone breaks your trust don't feel stupid for trusting them. You didn't do anything wrong.
